Observations of solar disk with two different viewing angles (SDO and STEREO), provide the same structures at different locations. We used the tie-pointing method in SCC_MEASURE routine of
SECHHI available in SSWIDL to locate the positions of these same structures in two different images ([1]}; [2]}). In this routine we reconstruct the three dimensional picture of the ejecting feature by clicking the same
feature on both STEREO and SDO images. A corresponding LOS crosses the identified feature in both images and the point at which this LOS meets is the tie-point.
Both SDO and STEREO images use the World Coordinate System keywords and are useful to determine the position of the specific solar feature and appears as a `+' sign.
